I'd purchased my 2003 Chevrolet Cavalier in like-new condition with ~20k miles. Months after I'd started driving the vehicle, I noticed that when I would put the transmission into neutral(manual transmission), the rpm would drop well below 1000 and sometimes it would stall. When it would stall, it wouldn't start again for a few minutes of sitting. I had the vehicle looked at and no one could find a problem. This problem didn't occur at a regular interval, but instead happened randomly at least once within 2 or 3 months time. I have had the car for 4. 5 years and the fuel pump has stopped operating completely. The problem wasn't apparent until I tried starting my vehicle on the morning of November 8th 2009 and the vehicle would not start. The starter was functioning properly, but the electronic fuel injection unit was making a different noise. After having the vehicle evaluated, it was determined that the fuel pump had become inoperable. The replacement fuel pumps price ranges between $150-250 on average and labor would cost more. By doing a little research, it's obvious that this is a common case. An o. E. M. Fuel pump on a car under 75k miles should last longer than 5 years before deterioration.
